The core partner data centres that are integrated in NorDataNet are listed in https://www.nordatanet.no/en/node/69. In addition to this NorDataNet harvests information on relevant datasets from a number of other data centres. The data centre responsible for the data presented is usually (but not always) listed in the discovery metadata. In essence NorDataNet is an aggregating service that combines information from a number of existing data centres.
Citation of data and service
If you use data retrieved through this portal, please acknowledge our funding source:
Research Council of Norway, project number 245967/F50, Norwegian Scientific Data Network.
Always remember to cite data when used!
Citation information for individual datasets is often provided in the metadata. However, not all datasets have this information embedded in the discovery metadata. On a general basis a citation of a dataset include the same components as any other citation:
author, title,
year of publication,
publisher (for data this is often the archive where it is housed),
edition or version,
access information (a URL or persistent identifier, e.g. DOI if provided)
All partner repositories of NorDataNet support Digital Object Identifiers (DOI), but not all datasets are minted. Whether or not minted depends often on source of the data (e.g. operational data are often yet not minted). However, all data centres support persistent identifiers according to local systems. The information required to properly cite a dataset is normally provided in the discovery metadata the datasets.
Brief user guide
The Data Access Portal has information in 3 columns. An outline of the content in these columns is provided above. When first entering the search interface, all potential datasets are listed. Datasets are indicated in the map and results tabulation elements which are located in the middle column. The order of results can be modified using the "Sort by" option in the left column. On top of this column is normally relevant guidance information to user presented as collapsible elements.
If the user want to refine the search, this can be done by constraining the bounding box search. This is done in the map - the listing of datasets is automatically updated. Date constraints can be added in the left column. For these to take effect, the user has to push the button marked search. In the left column it is also possible to specific text elements to search for in the datasets. Again pushing the button marked "Search" is necessary for these to take action. Complex search patterns can be constructed using logical operators identified in the drop down menu with and phrases embedded in quotation marks. Prefixing a phrase with '-' negates the phrase (i.e. should not occur in the results). Searches are case insensitive.
Other elements indicated in the left and right columns are facet searches, i.e. these are keywords that are found in the datasets and all datasets that contain these specific keywords in the appropriate metadata elements are listed together. Further refinement can be done using full text, date or bounding box constraints. Individuals, organisations and data centres involved in generating or curating the datasets are listed in the facets in the right column. The combination of search fields (including facets) is based on a logical "AND" combination of the fields, i.e. all conditions are fulfilled for the results provided.

Abstract:
CTD temperature, salinity, dissolved oxygen and light transmission at 191 stations in the Arctic Ocean
High quality physical and chemical data in the Southern Ocean is critical for improved understanding of future climates. As a part of Japanese Antarctic Research Expedition (JARE) 58 research project, we have obtained high quality Conductivity Temperature Depth (CTD) and water sampling data (salinity, dissolved oxygen, nutrients) at 5 sites locate along 110E transect, of which southern end reaching sea ice edge. Also, by using Thermosalinograph (TSG), sea surface temperature and salinity are continuously obtained all along cruise track taken between Fremantle and Hobart, except for Australian Exclusive Economic Zone. Data quality are validated by following instruments and methods of Global Ocean Ship-Based Hydrographic Investigation Program (GO-SHIP) recommendation as far as possible. CTD (including XCTD) and water sampling data are provided in Exchange formats for WOCE Hydrographic Program (WHP) CTD and bottle data and TSG data in simple .csv format.
The mooring collected data between January 16th of 2012 to December 18th of 2012 and the CTD casts were done between January 18th of 2012 and January 29 of 2012.
Physical oceanographic observations were conducted during the R/TV Umitaka-Maru cruise to describe the watermass properties in the Weddell-Enderby Basin, East Antarctica. Conductivity Temperature Depth (CTD)/ Rosette Multi-Sampler (RMS) observations were completed for 39 stations in January 2009. Seabird SBE911plus CTD system/SBE32 RMS was used.Water samples for salinity were collected to calibrate the CTD sensors. Bottle salinity analysis was done by Autosal8400B (Guildline). Bottle salinity shows a generally good determination.
Physical oceanographic observations were conducted during the R/TV Umitaka-Maru cruise to describe the watermass properties in the Weddell-Enderby Basin, East Antarctica. Conductivity Temperature Depth (CTD)/ Rosette Multi-Sampler (RMS) observations were completed for 23 stations from December 2007 to January 2008. Seabird SBE911plus CTD system/SBE32 RMS was used.Water samples for salinity were collected to calibrate the CTD sensors. Bottle salinity analysis was done by Autosal8400B (Guildline). Bottle salinity shows a generally good determination.
Connecting all major ocean basins, the Southern Ocean is pivotal in the meridional overturning circulation of the global oceans. High quality physical and chemical oceanographic data in the Southern Ocean are thus critical for improved understanding of future climates. As a part of the 59th Japanese Antarctic Research Expedition research project, we have obtained high quality Conductivity Temperature Depth (CTD) and water sampling data (salinity, dissolved oxygen, and nutrients) at 6 sites located along 110 degree E transect, the southern end of which reached the sea ice edge. Sea surface temperature and salinity were continuously obtained with a Thermosalinograph (TSG) along cruise track taken between Ports of Fremantle and Hobart, except for Australian Exclusive Economic Zone. Data quality was validated by following as far as possible the recommendation for instruments and methods of Global Ocean Ship-Based Hydrographic Investigation Program. CTD and water sampling data are provided in Exchange formats for World Ocean Circulation Experiment Hydrographic Program CTD and bottle data; TSG data are in simple .csv format.
The main target of physical oceanography section during this R/V Hakuho-Maru cruise is to describe the water properties of the Cape Darnley Bottom Water (CDBW) - its origin, distribution, and long-term change. The target area is the region spanning from a deep part in the Weddell-Enderby Basin to shallower continental shelf region off Cape Darnley, East Antarctica. Conductivity Temperature Depth (CTD)/ Rosette Multi-Sampler (RMS) observations were conducted for 17 stations in February 2016. Seabird SBE911plus CTD system/SBE32 RMS was used.Water samples for salinity were collected to calibrate the CTD sensors. Bottle salinity analysis was done by Autosal8400B (Guildline) at Laboratory No.5. Measurements were done for 122 standard/samples on 17-18 February after all CTD casts completed. Room temperature were controlled within 22.5-23.1 degC range. Bottle salinity shows a generally good determination. Some outlier values are found for near-surface waters. It seems to have a slight pressure dependency. Compared to the large signal, no clear temporal/inter-station drift was found. Hence the pressure-dependent offset was corrected for CTD output.
The Southern Ocean connects all major ocean basins and plays a pivotal role in the meridional overturning circulation of the global oceans. High-quality physical (temperature, salinity, and dissolved oxygen) and chemical (nutrients) oceanographic data from the Southern Ocean are thus critical for an improved understanding of future climates. As part of the 60th Japanese Antarctic Research Expedition, and also as a part of annually conducted monitoring observations, we have obtained high-quality Conductivity-Temperature-Depth (CTD) and water sampling data (salinity, dissolved oxygen, and nutrients) at 6 sites located along a 110E transect in January 2019. Sea surface temperature and salinity were obtained continuously with a thermosalinograph (TSG) along the cruise track between the ports of Fremantle and Hobart, except within the Australian Exclusive Economic Zone. Data quality was validated by following as far as possible the recommendations for instruments and methods of the Global Ocean Ship-Based Hydrographic Investigation Program.
This is a conductivity, temperature, pressure, and dissolved oxygen dataset obtained by Umitaka-Maru cruise during the year of 2011-2019. For the purpose of analysing long term variability, only the data observed along 110E and 115E are selected. Also, only the data observed in the region south of 57S, where the spacial density of observation increases, are selected. All the data were observed in January. The methodologies for data processing, water sampling, measurements, and data calibration followed the recommendations for the instruments and methods of the Global Ocean Ship-Based Hydrographic Investigation Program (GO-SHIP) to the greatest extent possible.
The Nansen Legacy cruise Q3 (Q3: 3rd quarter of the year) initiated the seasonal investigation of the northern Barents Sea and adjacent Arctic Basin. The cruise focused on comparing the state of the physical, chemical and biological conditions along the Nansen Legacy main transect in open waters and within the sea ice, addressing objectives of the work packages Physical drivers (Research Foci 1), Human impact (Research Foci 2) and The living Barents Sea (Research Foci 3). These data are created from the CTD data published by NMDC for the whole cruise (https://doi.org/10.21335/NMDC-1107597377). The values have not be changed.
The Nansen Legacy cruise Q2 (Q2: 2nd quarter of the year) was part of the seasonal investigation of the northern Barents Sea and adjacent Arctic Basin. The cruise was conducted during the spring period a biologically critical time window when a large part of the annual primary production occurs and focused on comparing the physical, chemical and biological conditions along the Nansen Legacy main transect in open waters and within the sea ice. The cruise addressed objectives of the work packages Physical drivers (Research Focus 1), Human impact (Research Focus 2), The living Barents Sea (Research Focus 3) and Technology and method development (Research Activity C). These data are created from the CTD data published by NMDC for the whole cruise (https://doi.org/10.21335/NMDC-515075317). The values have not be changed.
